Abstract (en)
[origin: EP2133538A1] The gas-conveying rotary valve (30) has a torsion spring (5) formed as an energy storage. An end of the torsion spring is movable at a valve steering body (17) around a rotational axis (1). The valve steering body has a valve closing organ (6) and a shaft (7). The other end of the torsion spring is fixed at a place of the rotary valve. The torsion spring is curved such that the torsion spring holds one or multiple torsion axes (2,3,4). The torsion spring has an axially parallel component and an axially perpendicular component.
